X.25 is an International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) standard protocol suite for connecting to packet switched Wide Area Networks (WAN) that use, for example, leased lines and a Integrated Services Digital Network (ISDN) system as the networking hardware. Devices utilizing the X.25 protocol suite include Data Terminal Equipment (DTE), Data Circuit-Terminating Equipment (DCE), and a Packet Switching Exchange (PSE). The X.25 protocol suite may be utilized in conjunction with any one of a number of other protocols and associated networks including the Transmission Control Protocol (TCP), Internet Protocol (IP) (collectively TCP/IP), an Asymmetric Digital Subscriber Line (ADSL), or ISDN.
